From Wikipedia:

Ridley Scott’s Final Cut (2007, 117 minutes) or the 25th-Anniversary Edition, briefly released by Warner Bros. Pictures theatrically on October 5, 2007 and then released on DVD, HD DVD, and Blu-ray in December 2007 (UK December 3; US December 18) is the only version over which Ridley Scott had artistic control, as the Director’s Cut production did not place Scott in charge.

So I prefer the Final Cut when it’s available, or any other cut without the voice-over.
